HC Deb 20 November 1940 vol 365 cc2007-8W
Mr. R. Gibson

asked the Home Secretary whether he is aware that in certain parts of Scotland there is serious discontent regarding the inefficiency of the working of the air-raid precautions warning system and what steps he proposes to take to make the system effective?

Mr. Mabane

No, Sir, I am not aware of serious discontent of the character suggested, but I am aware of a number of cases of attacks having developed before the sounding of the siren. It must be borne in mind that the air-raid warning system is not automatic but depends on many human factors. While, as has been made clear in the House on several occasions, no guarantee can be given that the presence or intentions of every hostile aeroplane will be correctly interpreted, I can assure my hon. Friend that all those concerned make every effort to ensure the effective operation of the warning system.
